2.6. Dual/Single Mode
A single or dual FIRE indication can trigger the VFC relay, fire-extinguisher and fire-relay. Single or
dual mode is configurable with two dip-switches.
Any detection zone alarm condition will operate audible and visual alarm indications as follows:

A single alarm condition on a detection line causes an internal pulsing alarm sound. The VFC
and Fire relay and extinguisher are operated according to the dip-switch settings.

A double alarm condition on a detection line causes a fast pulsing internal alarm sound. The
VFC relay, Fire relay and extinguisher are operated according to the dip-switch settings.

The alarm led flashes to indicate the activated alarm zone (1 flash per second indicates zone
1, 2 flashes per second indicates zone 2 and 3 flashes per second indicates both zones).
2.7. Timer Settings
A count-down timer is used to wait a certain amount of time before extinguisher enabling in case of
aFIRE alarm. This timer can be set with the use of the TIME-SWITCH dip-switches. The timer is
changeable between 0 and 30 seconds, with steps of 5 seconds.
The TIME-SWITCH dip-switches can also be used to set the device in No-AUTO release state. In
this state, only pressing the fire-buttons on the device or the external extinguishing release button
can (immediately) enable the fire-extinguisher. In this case, FIRE alarms from the detector zones
will only trigger the FIRE and VFC relays (and not the release the fire-extinguisher).
2.8. Ignition Mode
When the system is supplied with power on the normal inputs, it also monitors the ignition input (if
not chosen otherwise with the dip-switch settings). In normal usage, the ignition line feeds the
system with roughly the same voltage as the input lines. This means the ignition is engaged.
Upon disengaging of the ignition, the on LED will start to blink and the VFC contact is operated (spin-
off). The system will wait for the delay time to pass, before entering parked mode. When parked
mode is enabled, the on LED will blink as a `heartbeat.
In PARKED mode, a single or dual (depending on the dip-switches) FIRE alarm immediately triggers
the extinguishers. When the ignition is re-enabled (even for a very short time), the system returns to
normal mode and the count-down timer is reset.
When the ignition is disabled, and within the spin-off time a FIRE alarm is raised, the complete spin-
off time is waited before the extinguishers are activated.
When the ignition mode is disabled and there is no external backup battery/power supply, connect
the battery input to the main input of the SFCP Rail to suppress a battery fault.
2.9. Battery Mode
Additionally on the normal power input, the SFCP Rail can be used with an external backup
battery/power supply. The user can choose to either use backup power, or use low-power mode
when the ignition disabled.
The battery power should be in the same range as the input power. Upon initialisation, the device will
check the normal power supply and note the nominal voltage. When the backup power supply gets
30% below the nominal Input power, the fault state is triggered and the fault LED and relay will be
activated.
This means that if the system normally uses a 12VDC Input, the battery should also supply 12VDC
input, or if the normal voltage is 24VDC, the battery should also supply 24VDC. If the SFCP Rail is
set to battery mode and the continuous power supply would fall off, the on LED will blink to warn the
user.
